考察广藿香挥发油β-环糊精包合物的制备工艺条件.以包合物的包合率作为评价指标,选择挥发油与β-CD的比例、包合温度、超声时间为主要影响因素,进行L9(34)正交试验,优化广藿香挥发油包合物的工艺条件.同时将广藿香挥发油β-环糊精包合物进行表征.结果表明:最佳包合工艺条件为挥发油与β-CD之比为1∶5、超声时间为45 m in、包合温度为50℃.在此条件下广藿香挥发油包合物的包合率可达80.9%.表征结果表明,广藿香挥发油β-环糊精包合物已经形成.因此,超声法制备广藿香挥发油的β-环糊精包合工艺合理可行.
【英文摘要】
The process research for the preparation of inclusion complex of herba pogostemonis volatile oil with β-cyclodextrin was reported.The ratio between volatile oil and β-cyclodextrin,as well as the ultrasonic reaction time and the inclusion temperature was optimized by using the inclusion percentage as measurement through L9(34) orthogonal experiment.Meanwhile,the inclusion complex of herba pogostemonis volatile oil with β-cyclodextrin was characterized,an inclusion of 80.9% was obtained,with 1∶5 as the ratio ...
